He was rather below the middle size, in youth inclined to stoutness, lean in old age, but of vigorous and active habits. An expression of keen intelligence lighted up his features, and his large, sparkling grey eyes darted penetrating glances at every one who approached him. In his later years an old blue uniform with red facings was his usual dress, and on his breast was generally some Spanish snuff, of which he consumed large quantities. He shared many of the chief intellectual tendencies of his age, having no feeling for the highest aspirations of human nature, but submitting all things to a searching critical analysis. Of Christianity he always spoke in the mocking tone of the "enlightened" philosophers, regarding it as the invention of priests; but it is noteworthy that after the Seven Years' War, the trials of which steadied his character, he sought to strengthen the church for the sake of its elevating moral influence. In his judgments of mankind he often talked as a misanthrope. He was once conversing with Sulzer, who was a school inspector, about education. Sulzer expressed the opinion that education had of late years greatly improved. "In former times, your Majesty," he said, "the notion being that mankind were naturally inclined to evil, a system of severity prevailed in schools; but now, when we recognize that the inborn inclination of men is rather to good than to evil, schoolmasters have adopted a more generous procedure." "Ah, my dear Sulzer," replied the king, "you don't know this damned race" ("Ach, mein lieber Sulzer, er kennt nicht diese verdammte Race"). This fearful saying unquestionably expressed a frequent mood of Frederick's; and he sometimes acted with great harshness, and seemed to take a malicious pleasure in tormenting his acquaintances. Yet he was capable of genuine attachments. He was beautifully loyal to his mother and his sister Wilhelmina; his letters to the duchess of Gotha are full of a certain tender reverence; the two Keiths found him a devoted friend. But the true evidence that beneath his misanthropical moods there was an enduring sentiment of humanity is afforded by the spirit in which he exercised his kingly functions. Taking his reign as a whole, it must be said that he looked upon his power rather as a trust than as a source of personal advantage; and the trust was faithfully discharged according to the best lights of his day. He has often been condemned for doing nothing to encourage German literature; and it is true that he was supremely indifferent to it. Before he died a tide of intellectual life was rising all about him; yet he failed to recognize it, declined to give Lessing even the small post of royal librarian, and thought _Goetz von Berlichingen_ a vulgar imitation of vulgar English models. But when his taste was formed, German literature did not exist; the choice was between Racine and Voltaire on the one hand and Gottsched and Gellert on the other.
